Be it known that I, WILLISTON CONNER, of'Rensselaerville, in the county of Albany, and State of New York, have invented a new and improved Sap-Spile; and I do hereby declare that the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being. had to the accompanying drawings, forming part of this specicatiom Figure 1 is a side view of my improved spile.

My invention has for its object to furnish an improved sap-spile, simple in construction, effective in operation, and whichca'n bemanufaetured and sold for a very stnall'amo'unt; and it consists in a spile cast with a circular flange u'pon its inner end, the edge of which is bevelled, and from the inner side of which project two prongs; andn the combination with 'said 4spile of an inclined notched arm or longitudinal' angeg. the Whole being constructed and arranged as hereinafter more fully'described. v

.A is the body or stem oi the spile, which is made hollow,-or with a channel leading longitudinally through its central part, and the outer endof which may have a head or bulb, a, formed upon it to prevent it from'being battered in driving it into the hole in the tree. Upon the inner end of the body or stem A is formed a circular 'lange, Bfof such a size as to fit into the mouth of the auger-hole bored in theA tree for its reception. The edge of the ange or shoulder B is bevel-led o, as 'sho-wn in figs. 1, 3, and 4, so that it may itclosely into the hole in the treehand prevent the escape of the sap around the edge of said ange B. Upon theinner side of the flange-B are cast two prongs, C, which enter the hole in the tree, and rest against the upper and lower sides o f said hole, so as to support the spile in position even when supporting a pail or other vessel to receive the sap. If -desired, an inclined notched arm or ange, D, may be cast upon the upper side o f the stem or body A of the spiie, asA shown in iig. 4, so that the pail or other vessel may be supported at a greater or less height, as the circumstances of the case may render advisable.

I claim asnew, and desire to secure by Letters Patent- 1.. An'improved sap-spile, cast hollow, 'and with acircular lange, B, cast upon its inner end, said flange .having its edge bevelled, and'having two prongs, C, cast upon its inner side,'substantially as herein shown .and described, and for the purposes set forth.

2. The combination of the inclinedl and notched arm or flange D with the body or stem A of the yspile, substantially as herein shown and described, and for the purpose set forth.
